Monitoring the therapeutic alliance throughout treatment can improve client outcomes and lead to improved care. The individual, couple, and family versions of the intersession alliance measure (IAM) were developed to facilitate routine monitoring of the expanded therapeutic alliance. Psychometric properties of the three versions of the IAM were examined using a clinical sample. Participants were drawn from clinics in the United States participating in the Marriage and Family Therapy Practice Research Network. Using this sample, results indicate that items on each version of the IAM load on one factor, are invariant across sex, and that each version has good internal consistency, test–retest reliability, and concurrent validity. The IAM-C and IAM-F also have good predictive validity, while the IAM-I has more limited evidence for its predictive validity. These results suggest that the IAMs are valid and reliable measures that can facilitate the routine monitoring of the expanded therapeutic alliance in psychotherapy.

闭会期间联盟措施的验证：个人、夫妻和家庭版本

在整个治疗过程中监测治疗联盟可以改善客户的治疗结果并改善护理。制定个人、夫妻和家庭版本的闭会期间联盟措施 (IAM) 是为了促进对扩大的治疗联盟的常规监测。使用临床样本检查了 IAM 的三个版本的心理测量特性。参与者来自参与婚姻和家庭治疗实践研究网络的美国诊所。使用该样本，结果表明每个版本的 IAM 负载在一个因素上的项目在不同性别之间是不变的，并且每个版本都具有良好的内部一致性、重测可靠性和并发有效性。 IAM-C 和 IAM-F 也具有良好的预测有效性，而 IAM-I 的预测有效性证据更为有限。这些结果表明，IAM 是有效且可靠的措施，可以促进对心理治疗中扩大的治疗联盟的常规监测。
